Active phase separation from concentration-dependent diffusion in chemical networks

Giulia Pisegna, Ramin Golestanian

Active phase separation in living systems is ubiquitous, yet the microscopic origins of the non-equilibrium terms in active field theories remain largely unknown. Here, starting fr…

Scaling behavior in non-reciprocal and odd conserved dynamics near criticality

Martin Kjøllesdal Johnsrud, Giulia Pisegna, Ramin Golestanian

In recent years, non-reciprocity has been explored as a ubiquitous manifestation of non-equilibrium activity at the microscopic scales for various active matter systems, from mixtu…

Spinning mixtures: nonreciprocity transfers chirality across scales in scalar densities

Giulia Pisegna, Suropriya Saha

Mixtures of chiral active particles provide a minimal setting where nonreciprocity and chirality intertwine to shape collective dynamics. Here we show that nonreciprocal interactio…

Non-reciprocal mixtures in suspension: the role of hydrodynamic interactions

Giulia Pisegna, Navdeep Rana, Ramin Golestanian +1

The collective chasing dynamics of non-reciprocally coupled densities leads to stable travelling waves which can be mapped to a model for emergent flocking. In this work, we couple…

Hydrodynamic stresses in a multi-species suspension of active Janus colloids

Gennaro Tucci, Giulia Pisegna, Ramin Golestanian +1

A realistic description of active particles should include interactions with the medium, commonly a momentum-conserving simple fluid, in which they are suspended. In this work, we…

Emergent polar order in non-polar mixtures with non-reciprocal interactions

Giulia Pisegna, Suropriya Saha, Ramin Golestanian

Phenomenological rules that govern the collective behaviour of complex physical systems are powerful tools because they can make concrete predictions about their universality class…
